Stress is one of the factors that may affect skin. And when you don't get a break for it, the results could be disastrous. So make sure you get enough sleep - at least 8 hours every night. During a sleep cycle, the body recovers itself from daily stress and when you cut short those hours of sleep, the skin could age prematurely. On the other hand, I'm sure you noticed how after a good night's sleep you wake up with fresh-looking skin. So make sure you get at least 8 hours of rest per night.
